i bought an extra pulsar 1 with the explicit purpose of running crossover filters created on SDK to help design active crossovers and delays for amplifier-per-driver speakers.
Just to add to the comment above, the described method produces a notch filter which works well with zero or low resonance. To achieve a notch filter which works well at higher quality factors, try phase inverting the BP signal from your multimode filter & mixing it with the filter's input signal. This actually produces a notch filter which works well at both high & low quality factors.<Shroomz> wrote:You could also connect the LP & HP outputs of a multimode filter to a x-fade module, getting a new filter type which has a controllable curve. In the 0 x-fade position the new filter will be a notch or bandreject filter.
Neutron, that sounds interesting.
